[QUOTE="jstutzman, post: 6299243, member: 613809"] I do not have in depth knowledge of the JL circuit, but what you are saying does not make sense under normal circumstances. When you have the amp disconected and short the positive termanal, it should do nothing but discharge the power supply caps. This should have no effect on the turn on circuit. Althouh it shouldnt, it is not entirely impossible for JL to have designed a remote turn on circuit that is a little more complicated than the standard that most amps use. discharging the pwr supply caps should have no effect, but maybe when you gnd the positive terminal, something in the amp gets reset and then the pwr on ckt starts working correctly. If you know what your doing and what your saying is true, i would contact JL and potentially get that thing repaired becuase something is not right. Perhaps you could do this Mini experiment. Unhook your amp. Take a volt meter and check the voltage from positive wire to negative wire and make sure it is 12.5 V ish, im assuming car will be off. Then check the remote turn on wire to insure it is 12 V.
